Did anybody meet malfunction of Sigma HSM

Three weeks ago the HSM of my Sigma 70-200/2.8 couldn't work for a while.
Later I tried full battery and focusing while turning the focus ring, it was able to work again. But when it goes to the furthest end there is some subtle noise.
Does anybody have the same problem before? Or it is just due to the low battery, in other words, HSM is very energy-consuming?

send it in under warranty repair? cameralensrentals.com said they've had a lot of 70-200HSM failures so they're going to be adding more Tamron 70-200 rentals instead :-P
